Abstract
The utility model belongs to a high-pressure air cooler tube box of a tongue piece sealing structure. The high-pressure air cooler tube box is mainly used for a petrochemical industry hydrogenation device and composed of an inlet tube, a tube plate, a cover plate, a tongue piece base plate, a heat exchanging tube and the like. The high-pressure air cooler tube box is characterized in that the tongue piece base plate is additionally arranged between the sealing face of the tube plate and the sealing face of the cover plate, the tongue piece base plate is characterized in that a concave-convex sealing structure is adopted for two base plate bodies for sealing, and sealing welding is carried out on an extending-out outer circle of the tongue piece base plate after the tube plate and the cover plate are assembled. Grooves are formed in the inner sides of the tube plate and the cover plate to form inner-box medium buffering space. The high-pressure air cooler tube box has the advantages that the sealing reliability is improved through the tongue piece base plate and sealing welding, a welding connector of the heat exchanging tube and the tube plate is beneficial to various kinds of detection, the detachable cover plate brings convenience to overhauling, welding beads of the overall tube box are fewer, and welding joint quality accidents are effectively reduced.
Description
Technical field
The utility model belongs to a kind of air cooling equipment for oil, chemical industry, coal chemical technology, relates in particular a kind of tongue piece hermetically-sealed construction high pressure high-pressure air cooler bobbin carriage of main use at petrochemical industry hydrogenation plant.
Background technology
Air cooling heat exchanger (abbreviation air cooler) is a kind of energy-efficient cold exchange device, extensively practical in oil refining and chemical process, the area particularly lacking in water resource, is characterized in water saving, economize on electricity, floor space is little, heat exchange efficiency is high.The existing air cooler bobbin carriage generally using can be divided into two kinds of structures, it is respectively the board-like bobbin carriage of threaded plug type bobbin carriage and removable cover, the board-like bobbin carriage of removable cover is convenient to mechanical cleaning, and the pressure bearing is relatively low, and existing high-pressure air cooler bobbin carriage generally adopts threaded plug type structure.Because the corrosive medium of high-pressure air cooler applying working condition is extremely strong, and threaded plug type bobbin carriage welding bead is more, and in order to control the weldquality of casing surrounding, the welding point of heat exchanger tube and tube sheet can only adopt Deep Hole Welding, and leakage accident easily occurs at weld seam position.
The domestic corrosion resistance that generally adopts the external imported material of overall high alloy to improve material at present, but material cost is higher, and delivery cycle is long, because the inconvenience of threaded plug type bobbin carriage internal structure is cleaned, in bobbin carriage medium period duration of runs long after especially easily at the welding point of heat exchanger tube and tube sheet, channel cover and pipe sheet weld joint, plug connecting portion form fouling corrosion and produce the generation that leakage causes security incident, bring larger economic loss.
Also have CN201034448Y, CN201093920Y, CN202793057U etc. through the retrieval prior art relevant to the utility model, but the related channel structure of these patents and seal form and the utility model there are in essence different.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of tongue piece hermetically-sealed construction high-pressure air cooler bobbin carriage, can, in meeting bearing strength, reduce welding bead, improves sealing property, is convenient to disassembly, cleaning.
For achieving the above object, a kind of tongue piece hermetically-sealed construction high-pressure air cooler bobbin carriage that the utility model provides is made up of tube sheet, cover plate, tongue piece backing plate, heat exchanger tube, inside tube sheet and cover plate, machined grooves forms case in-vivo medium cushion space, and the feature of the sealing of described tube sheet and cover plate is to adopt tongue piece backing plate and backing plate to stretch out the double sealing structure of outer ring seal weld in the middle of sealing surface.
Described tongue piece backing plate is made up of two backing plates, and wherein a backing plate is processed two place's raised lines, stretches out in tube sheet and cover plate when the assembling of tongue piece backing plate.
The advantage of the utility model high-pressure air cooler bobbin carriage is:
The bobbin carriage of removable cover plank frame, is convenient to clean the inner dirt of bobbin carriage, and the welding point of heat exchanger tube and tube sheet adopts exterior angle postwelding to be convenient to all kinds of Non-Destructive Testings, avoids quality of weld joint hidden danger.
By the bobbin carriage after tube sheet and cover plate assembling, reduce welding bead, avoid the existence of welding quality accident, can meet high voltage intensity operating mode simultaneously.
The dual-seal superior performance of tongue piece backing plate and seal weld.
Bobbin carriage is applicable to the use of various types of materials, particularly selects carbon steel material, has extended the service life of carbon steel high-pressure air cooler, has economic and practical.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of tongue piece hermetically-sealed construction of utility model high pressure high-pressure air cooler bobbin carriage
Fig. 2 is tongue piece backing plate sealed structural representation
Comprising: inlet tube 1, cover plate 2, tube sheet 3, tongue piece backing plate 4, studs 5, heat exchanger tube 6
Detailed description of the invention
Below in conjunction with accompanying drawing, 1 Fig. 2 describes embodiment of the present utility model; the principle that the present embodiment is just described of describing in the present embodiment and description; the utility model is not limited to embodiment; be combined with the expansion in field; the utility model will have and improves or change, these variations and to change will be all in claimed scope.
A kind of tongue piece hermetically-sealed construction high-pressure air cooler bobbin carriage, heat exchanger tube 6 adopts exterior angle automatic TIG Welding Machine to connect with tube sheet 3, welding quality stable, result of the test shows to be better than the deep hole welding that threaded plug type bobbin carriage adopts, and is convenient to carry out Non-Destructive Testing.Cover plate 2 carries out Pocket Machining with tube sheet 3 inner sides makes bobbin carriage casing no-welding-seam, and casing bearing strength is better than seamed casing.Tongue piece backing plate 4 stretches out outer ring at tongue piece backing plate 4 and carries out argon arc welding seal welding after adopting concavo-convex hermetically-sealed construction and tube sheet 3 and cover plate 4 use studs 5 fastening, effectively raises the sealing property of bobbin carriage.
